Courses Plus Student 5,745 PointsGenerate a random number?
What if i did not want to generate a random count for the array's. What if I only wanted to display the array's in order that they are written?

4,745 PointsI made it this way:
I declared a variable at the top
var elements: Int = 0
and then in the showFunFact function change the value of the variable to show the next array element
@IBAction func showFunFact() {
if elements != (factModel.facts.count - 1){
elements += 1
funFactLabel.text = factModel.facts[elements]
}
else {
elements = 0
funFactLabel.text = factModel.facts[elements]
}
}
I hope it helps :)

14,371 Pointsyou could do a For loop that would loop over each index of the array.
Example:
for index in 0...array.count {
// Do something
}
